    It is not the case that Earman, Smeenk, and Wüthrich's own analysis shows no locally constructed time machine can satisfy this intersection condition without begging the question against wormhole topologies.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The claim conflates epistemological limits of local construction with metaphysical impossibility for time machines generally.
      ?

      Think about whether this reason is strong or weak

    • 2.Global consistency might be achievable through non-local constraints that don't presuppose specific topologies, refuting the begging-the-question charge.
      ?

      Think about whether this reason is strong or weak

    • 3.Earman et al. may only establish that *one particular approach* to construction is circular, not that all approaches necessarily are.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Local construction methods cannot impose global topological constraints without assuming the spacetime topology they aim to prove.
      ?

      Think about whether this reason is strong or weak

    • 2.The intersection condition requires consistency across entire wormhole geometries, which local procedures cannot verify independently.
      ?

      Think about whether this reason is strong or weak

    • 3.Earman et al. demonstrate that avoiding circularity demands topology-neutral initial conditions, which local construction violates.
      ?

      Think about whether this reason is strong or weak
